IMPROVEMENT IN THREAD DRESSING AND WINDING MACHINES.

Specification forming part of Letters Patent No. 139,521, dated J une 3,1873; application filed December 31, 1872.

To all whom it may concern:

Be it known that I, JAMES SHORT, of New Brunswick, in the county ofMiddlesex and State of New Jersey, have invented a new and ImprovedThread Dressing or Winding Machine, of which the following is aspecification:

Figure 1 is an end elevation of my improved thread dressing or windingmachine.

1 Fig. 2. is a side elevation of the same, and

Fig. 3 a detail top view, partly in section, of a portion of the same.

Similar letters of reference indicate corresponding parts.

The object of my invention is to furnish to thread manufacturers animproved threadwinding machine; and it consists in a certainconstruction and arrangement for facilitating the connection of the axleof the spool or thread-beam with the driving-shaft and its removal fromthe machine; in the provision for ready connection and disconnection ofthe weighted arms from those carrying frictionrollers and co-actin gwith a loose thread-pressing roller, as hereinafter fully described.

In the accompanying drawing, the letter A represents the frame of myimproved winding machine or winding attachment to a thread-dressingmachine. This frame is made of metal, wood, or both, of proper size andstrength to support the parts of the machine pertaining to thisinvention. B is the beam or spool around which the thread is to bewound. This beam is made hollow to receive a prismatic shaft, 0, whichhangs with its rounded portions that are formed near its ends, in thenotched upper parts of standards a b of the frame A. One extreme end, d,of this shaft 0 is squared and fits intoa square mortise, 6, formed inthe end of the shaft D, by which motion is conveyed to said shaft 0, andthereby also to the beam B that surrounds it. The mortise in the end ofthe shaft D is open at one side, and whenever the open portion isbrought in line with the notches in the standards a b, the shaft 0 withits beams, can be drawn forward and down the inclined surface .1? of thestandards until the beam or roll rests on the floor, (or other supportprovided for it,) when the shaft can be withdrawn provided withprojecting arms F F, whose rounded ends carry friction-rollers f f. G isa roller of suitable size, weight, and material, and about as long asthe beam B between its flanges, and is placed upon the beam andbei'ieath the friction-rollers f, of the arms F, as is fully indicatedin Fig. 2. H H are other arms projecting from the spindle E, andprovided with weights I I, which weights serve to draw the arms F uponthe roller G, and press the latter uponthe beam B.

V When thread is being wound upon thebeam, the beam is revolved in thedirection of the arrow 1, Fig. 2, and atthe same time the roller G willbe revolved in the direction of the arrow 2 of the same figure, and willthereby tend to retard the application of the thread---. that is to say,prevent the loose winding of the same. The weights I at the sametimeserve to press the roller Gdown upon the thread, allowing it, however,to be crowded gpward gradually by the thread that accumulates on thebeam; and thus to be moved from the lower position, in which it is shownby dotted lines in Fig. 2, into the upper position dotted into the samefigure.

In practice, I provide an automatic apparatus for stopping the machinewhen the threadbeam or spool is filled, and simultaneously supportingthe arms H so that the pins 9 may be removed. The friction-rollers fffacilitate the rotation of the roller G, and make the use of lubricatingmaterial unnecessary. I secure the arms H H upon the spindleE by meansof removable pins or bolts 9, to enable I the arms F to be swung quiteback clear of the beam, when it is necessary to remove the same, or elsethe arms F may be secured to the spindle E by such removable pins. Theweights I may be made adjustable on the arms H, so that, by setting'them, their effect on the roller G maybe regulated. The machine may bemade with but one arm F, and

2. The arms F, carrying friction-rollers f, and fixed on the shaft E, incombination with I the Weighted arms H mounted loosely on the -rojectingends of the shaft, and removable pins 9 for locking said parts together,in combination with the roller G and beam B, arranged as shown anddescrlbed, for the purpose specified. 1

3, The combination with the spoolB mounted on a removable spindle, theroller G placed above and resting on the spool and prevented fromlongitudinal movement by the flanges or disks of the spool, of thehinged arms F, provided with friction-rollers that bear on the body ofthe roller, and are retained against said rollers at all times by theweighted arms, as and for the purpose described.
